Constructor Details

ElementValueGen

protected ElementValueGen(int type,
 ConstantPoolGen cpGen)

Constructs an ElementValueGen.

Parameters:

type - the element value type.

cpGen - the constant pool.

Method Details

copy

public static ElementValueGen copy(ElementValue value,
 ConstantPoolGen cpool,
 boolean copyPoolEntries)

Creates an (modifiable) ElementValueGen copy of an (immutable) ElementValue - constant pool is assumed correct.

Parameters:

value - the element value to copy.

cpool - the constant pool generator.

copyPoolEntries - whether to copy pool entries.

Returns:

a copy of the element value.

readElementValue

public static ElementValueGen readElementValue(DataInput dis,
 ConstantPoolGen cpGen)
                                        throws IOException

Reads an element value from a DataInput.

Parameters:

dis - the data input stream.

cpGen - the constant pool.

Returns:

the element value read.

Throws:

IOException - if an I/O error occurs.

dump

public abstract void dump(DataOutputStream dos)
                   throws IOException

Dumps this element value to a DataOutputStream.

Parameters:

dos - the output stream.

Throws:

IOException - if an I/O error occurs.

getConstantPool

protected ConstantPoolGen getConstantPool()

Gets the constant pool.

Returns:

the constant pool.

getElementValue

public abstract ElementValue getElementValue()

Subtypes return an immutable variant of the ElementValueGen.

Returns:

an immutable variant of the ElementValueGen.

getElementValueType

public int getElementValueType()

Gets the element value type.

Returns:

the element value type.

stringifyValue

public abstract String stringifyValue()

Returns a string representation of the element value.

Returns:

a string representation of the element value.
