Method Detail
-
getNodeType
public final JsonNodeType getNodeType()
Description copied from class:JsonNodeReturn the type of this node- Specified by:
getNodeTypein classJsonNode- Returns:
- the node type as a
JsonNodeTypeenum value
-
numberType
public abstract com.fasterxml.jackson.core.JsonParser.NumberType numberType()
Description copied from class:BaseJsonNodeReturns code that identifies type of underlying numeric value, if (and only if) node is a number node.- Specified by:
numberTypein interfacecom.fasterxml.jackson.core.TreeNode- Overrides:
numberTypein classBaseJsonNode
-
numberValue
public abstract Number numberValue()
Description copied from class:JsonNodeReturns numeric value for this node, if and only if this node is numeric (JsonNode.isNumber()returns true); otherwise returns null- Overrides:
numberValuein classJsonNode- Returns:
- Number value this node contains, if any (null for non-number nodes).
-
intValue
public abstract int intValue()
Description copied from class:JsonNodeReturns integer value for this node, if and only if this node is numeric (JsonNode.isNumber()returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to int operates.
-
longValue
public abstract long longValue()
Description copied from class:JsonNodeReturns 64-bit long value for this node, if and only if this node is numeric (JsonNode.isNumber()returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to long operates.
-
doubleValue
public abstract double doubleValue()
Description copied from class:JsonNodeReturns 64-bit floating point (double) value for this node, if and only if this node is numeric (JsonNode.isNumber()returns true). For other types returns 0.0. For integer values, conversion is done using coercion; this may result in overflows withBigIntegervalues.- Overrides:
doubleValuein classJsonNode- Returns:
- 64-bit double value this node contains, if any; 0.0 for non-number nodes.
-
decimalValue
public abstract BigDecimal decimalValue()
Description copied from class:JsonNodeReturns floating point value for this node (asBigDecimal), if and only if this node is numeric (JsonNode.isNumber()returns true). For other types returnsBigDecimal.ZERO.- Overrides:
decimalValuein classJsonNode- Returns:
BigDecimalvalue this node contains, if numeric node;BigDecimal.ZEROfor non-number nodes.
-
bigIntegerValue
public abstract BigInteger bigIntegerValue()
Description copied from class:JsonNodeReturns integer value for this node (asBigDecimal), if and only if this node is numeric (JsonNode.isNumber()returns true). For other types returnsBigInteger.ZERO.- Overrides:
bigIntegerValuein classJsonNode- Returns:
BigIntegervalue this node contains, if numeric node;BigInteger.ZEROfor non-number nodes.
-
canConvertToInt
public abstract boolean canConvertToInt()
Description copied from class:JsonNodeMethod that can be used to check whether this node is a numeric node (JsonNode.isNumber()would return true) AND its value fits within Java's 32-bit signed integer type,int. Note that floating-point numbers are convertible if the integral part fits without overflow (as per standard Java coercion rules)NOTE: this method does not consider possible value type conversion from JSON String into Number; so even if this method returns false, it is possible that
JsonNode.asInt()could still succeed if node is a JSON String representing integral number, or boolean.- Overrides:
canConvertToIntin classJsonNode
-
canConvertToLong
public abstract boolean canConvertToLong()
Description copied from class:JsonNodeMethod that can be used to check whether this node is a numeric node (JsonNode.isNumber()would return true) AND its value fits within Java's 64-bit signed integer type,long. Note that floating-point numbers are convertible if the integral part fits without overflow (as per standard Java coercion rules)NOTE: this method does not consider possible value type conversion from JSON String into Number; so even if this method returns false, it is possible that
JsonNode.asLong()could still succeed if node is a JSON String representing integral number, or boolean.- Overrides:
canConvertToLongin classJsonNode
-
asText
public abstract String asText()
Description copied from class:JsonNodeMethod that will return a valid String representation of the container value, if the node is a value node (methodJsonNode.isValueNode()returns true), otherwise empty String.
-
asInt
public final int asInt()
Description copied from class:JsonNodeMethod that will try to convert value of this node to a Java int. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.If representation cannot be converted to an int (including structured types like Objects and Arrays), default value of 0 will be returned; no exceptions are thrown.
-
asInt
public final int asInt(int defaultValue)
Description copied from class:JsonNodeMethod that will try to convert value of this node to a Java int. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.If representation cannot be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
-
asLong
public final long asLong()
Description copied from class:JsonNodeMethod that will try to convert value of this node to a Java long. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.If representation cannot be converted to an long (including structured types like Objects and Arrays), default value of 0 will be returned; no exceptions are thrown.
-
asLong
public final long asLong(long defaultValue)
Description copied from class:JsonNodeMethod that will try to convert value of this node to a Java long. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.If representation cannot be converted to an long (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
-
asDouble
public final double asDouble()
Description copied from class:JsonNodeMethod that will try to convert value of this node to a Java double. Numbers are coerced using default Java rules; booleans convert to 0.0 (false) and 1.0 (true), and Strings are parsed using default Java language integer parsing rules.If representation cannot be converted to an int (including structured types like Objects and Arrays), default value of 0.0 will be returned; no exceptions are thrown.
-
asDouble
public final double asDouble(double defaultValue)
Description copied from class:JsonNodeMethod that will try to convert value of this node to a Java double. Numbers are coerced using default Java rules; booleans convert to 0.0 (false) and 1.0 (true), and Strings are parsed using default Java language integer parsing rules.If representation cannot be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
-
isNaN
public boolean isNaN()
Convenience method for checking whether this node is aFloatNodeorDoubleNodethat contains "not-a-number" (NaN) value.- Since:
