Class ConstantDoubleInfo

java.lang.Object

org.macroing.cel4j.java.binary.classfile.CPInfo

org.macroing.cel4j.java.binary.classfile.cpinfo.ConstantDoubleInfo

All Implemented Interfaces:

Node

public final class ConstantDoubleInfo
extends CPInfo

A ConstantDoubleInfo denotes a CONSTANT_Double_info structure in the constant_pool of a ClassFile structure.

The CONSTANT_Double_info structure was added to Java in version 1.0.2.

This class is not thread-safe.

Since:

1.0.0

Method Detail

copy

public ConstantDoubleInfo copy()

Returns a copy of this ConstantDoubleInfo instance.

Specified by:

copy in class CPInfo

Returns:

a copy of this ConstantDoubleInfo instance

toString

public java.lang.String toString()

Returns a String representation of this ConstantDoubleInfo instance.

Overrides:

toString in class java.lang.Object

Returns:

a String representation of this ConstantDoubleInfo instance

equals

public boolean equals(java.lang.Object object)

Returns true if, and only if, object is an instance of ConstantDoubleInfo, and that ConstantDoubleInfo instance is equal to this ConstantDoubleInfo instance, false otherwise.

Overrides:

equals in class java.lang.Object

Parameters:

object - an Object to compare to this ConstantDoubleInfo instance for equality

Returns:

true if, and only if, object is an instance of ConstantDoubleInfo, and that ConstantDoubleInfo instance is equal to this ConstantDoubleInfo instance, false otherwise

getDouble

public double getDouble()

Returns a double representation of this ConstantDoubleInfo instance.

Returns:

a double representation of this ConstantDoubleInfo instance

hashCode

public int hashCode()

Returns a hash code for this ConstantDoubleInfo instance.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code for this ConstantDoubleInfo instance

setDouble

public void setDouble(double value)

Sets a new double representation for this ConstantDoubleInfo instance.

Parameters:

value - the new double representation

write

public void write(java.io.DataOutput dataOutput)

Writes this ConstantDoubleInfo to dataOutput.

If dataOutput is an OutputStream (or any other type of stream), this method will not close it.

If dataOutput is null, a NullPointerException will be thrown.

If an I/O-error occurs, an UncheckedIOException will be thrown.

Specified by:

write in class CPInfo

Parameters:

dataOutput - the DataOutput to write to

Throws:

java.lang.NullPointerException - thrown if, and only if, dataOutput is null

java.io.UncheckedIOException - thrown if, and only if, an I/O-error occurs

write

public void write(Document document)

Writes this ConstantDoubleInfo to document.

If document is null, a NullPointerException may be thrown. But no guarantees can be made.

Specified by:

write in class CPInfo

Parameters:

document - the Document to write to

Throws:

java.lang.NullPointerException - thrown if, and only if, document is null

newInstance

public static ConstantDoubleInfo newInstance(double value)

Returns a new ConstantDoubleInfo.

Parameters:

value - the double representation of the new ConstantDoubleInfo instance

Returns:

a new ConstantDoubleInfo

filter

public static java.util.List<ConstantDoubleInfo> filter(Node node)

Returns a List with all ConstantDoubleInfos.

All ConstantDoubleInfos are found by traversing node using a simple NodeHierarchicalVisitor implementation.

If node is null, a NullPointerException will be thrown.

Parameters:

node - the Node to start traversal from

Returns:

a List with all ConstantDoubleInfos

Throws:

java.lang.NullPointerException - thrown if, and only if, node is null
