Method Detail

isNumber

public final boolean isNumber()

Overrides:

isNumber in class JsonNode

Returns:

True if this node represents a numeric Json value

getNumberType

public abstract JsonParser.NumberType getNumberType()

Description copied from class: JsonNode

If this node is a numeric type (as per JsonNode.isNumber()), returns native type that node uses to store the numeric value.

Overrides:

getNumberType in class BaseJsonNode

getNumberValue

public abstract Number getNumberValue()

Description copied from class: JsonNode

Returns numeric value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true); otherwise returns null

Overrides:

getNumberValue in class JsonNode

Returns:

Number value this node contains, if any (null for non-number nodes).

getIntValue

public abstract int getIntValue()

Description copied from class: JsonNode

Returns 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.

Overrides:

getIntValue in class JsonNode

Returns:

Integer value this node contains, if any; 0 for non-number nodes.

getLongValue

public abstract long getLongValue()

Overrides:

getLongValue in class JsonNode

getDoubleValue

public abstract double getDoubleValue()

Overrides:

getDoubleValue in class JsonNode

getDecimalValue

public abstract BigDecimal getDecimalValue()

Overrides:

getDecimalValue in class JsonNode

getBigIntegerValue

public abstract BigInteger getBigIntegerValue()

Overrides:

getBigIntegerValue in class JsonNode

asText

public abstract String asText()

Description copied from class: JsonNode

Method that will return valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise empty String.

Specified by:

asText in class JsonNode

asInt

public int asInt()

Description copied from class: JsonNode

Method 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 can not be converted to an int (including structured types like Objects and Arrays), default value of 0 will be returned; no exceptions are thrown.

Overrides:

asInt in class JsonNode

asInt

public int asInt(int defaultValue)

Description copied from class: JsonNode

Method 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 can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

Overrides:

asInt in class JsonNode

asLong

public long asLong()

Description copied from class: JsonNode

Method 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 can not be converted to an long (including structured types like Objects and Arrays), default value of 0 will be returned; no exceptions are thrown.

Overrides:

asLong in class JsonNode

asLong

public long asLong(long defaultValue)

Description copied from class: JsonNode

Method 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 can not be converted to an long (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

Overrides:

asLong in class JsonNode

asDouble

public double asDouble()

Description copied from class: JsonNode

Method 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 can not be converted to an int (including structured types like Objects and Arrays), default value of 0.0 will be returned; no exceptions are thrown.

Overrides:

asDouble in class JsonNode

asDouble

public double asDouble(double defaultValue)

Description copied from class: JsonNode

Method 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 can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

Overrides:

asDouble in class JsonNode
