Method Detail

cloneMutable

public static DataValue cloneMutable(DataValue value)

Return (nullable) A clone of value if it is mutable, or value if it is immutable.

Parameters:

value - (nullable) Value to be cloned.

Returns:

(nullable) A clone of value if it is mutable, or value if it is immutable.

equals

public boolean equals(java.lang.Object value)

Return true if this object is equal to value.

Overrides:

equals in class java.lang.Object

Parameters:

value - (nullable) The value to compare with.

Returns:

true if this object is equal to value.

getDataType

public abstract DataType getDataType()

Return data type of the wrapped value.

Returns:

Data type of the wrapped value.

getTypeCode

public int getTypeCode()

Return data type code of the wrapped value, equivalent to dataType.code.

Returns:

Data type code of the wrapped value, equivalent to dataType.code.

hashCode

public int hashCode()

Hash this data value to a number.

Overrides:

hashCode in class java.lang.Object

Returns:

Any value in the range of type int.

toString

public abstract java.lang.String toString()

Convert this data value to a string. If the DataValue.dataType is defined by XML Schema Part 2: Datatypes, then the corresponding lexical format is used. JSON format is used for structured values (arrays and objects).

Overrides:

toString in class java.lang.Object

Returns:

Lexical representation of this data value.
