Method Detail

getLocalVariableTypeTable

public java.util.List<LocalVariableTypeTableAttribute.LocalVariableType> getLocalVariableTypeTable()

Returns a List with all currently added LocalVariableTypes.

Modifying the returned List will not affect this LocalVariableTypeTableAttribute instance.

Returns:

a List with all currently added LocalVariableTypes

copy

public LocalVariableTypeTableAttribute copy()

Returns a copy of this LocalVariableTypeTableAttribute instance.

Specified by:

copy in class AttributeInfo

Returns:

a copy of this LocalVariableTypeTableAttribute instance

toString

public java.lang.String toString()

Returns a String representation of this LocalVariableTypeTableAttribute instance.

Overrides:

toString in class java.lang.Object

Returns:

a String representation of this LocalVariableTypeTableAttribute instance

accept

public boolean accept(NodeHierarchicalVisitor nodeHierarchicalVisitor)

Accepts a NodeHierarchicalVisitor.

Returns the result of nodeHierarchicalVisitor.visitLeave(this).

If nodeHierarchicalVisitor is null, a NullPointerException will be thrown.

If a RuntimeException is thrown by the current NodeHierarchicalVisitor, a NodeTraversalException will be thrown with the RuntimeException wrapped.

This implementation will:

• throw a NullPointerException if nodeHierarchicalVisitor is null.
• throw a NodeTraversalException if nodeHierarchicalVisitor throws a RuntimeException.
• traverse its child Nodes, if it has any.

Parameters:

nodeHierarchicalVisitor - the NodeHierarchicalVisitor to accept

Returns:

the result of nodeHierarchicalVisitor.visitLeave(this)

Throws:

NodeTraversalException - thrown if, and only if, a RuntimeException is thrown by the current NodeHierarchicalVisitor

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

equals

public boolean equals(java.lang.Object object)

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

Overrides:

equals in class java.lang.Object

Parameters:

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

Returns:

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

getAttributeLength

public int getAttributeLength()

Returns the attribute_length of this LocalVariableTypeTableAttribute instance.

Specified by:

getAttributeLength in class AttributeInfo

Returns:

the attribute_length of this LocalVariableTypeTableAttribute instance.

getLocalVariableTypeTableLength

public int getLocalVariableTypeTableLength()

Returns the local_variable_type_table_length of this LocalVariableTypeTableAttribute instance.

Returns:

the local_variable_type_table_length of this LocalVariableTypeTableAttribute instance.

hashCode

public int hashCode()

Returns a hash code for this LocalVariableTypeTableAttribute instance.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code for this LocalVariableTypeTableAttribute instance

addLocalVariableType

public void addLocalVariableType(LocalVariableTypeTableAttribute.LocalVariableType localVariableType)

Adds localVariableType to this LocalVariableTypeTableAttribute instance.

If localVariableType is null, a NullPointerException will be thrown.

Parameters:

localVariableType - the LocalVariableTypeTableAttribute.LocalVariableType to add

removeLocalVariableType

public void removeLocalVariableType(LocalVariableTypeTableAttribute.LocalVariableType localVariableType)

Removes localVariableType from this LocalVariableTypeTableAttribute instance.

If localVariableType is null, a NullPointerException will be thrown.

Parameters:

localVariableType - the LocalVariableTypeTableAttribute.LocalVariableType to remove

write

public void write(java.io.DataOutput dataOutput)

Writes this LocalVariableTypeTableAttribute 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 AttributeInfo

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

filter

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

Returns a List with all LocalVariableTypeTableAttributes.

All LocalVariableTypeTableAttributes 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 LocalVariableTypeTableAttributes

Throws:

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

newInstance

public static LocalVariableTypeTableAttribute newInstance(int attributeNameIndex)

Returns a new LocalVariableTypeTableAttribute instance.

If attributeNameIndex is less than or equal to 0, an IllegalArgumentException will be thrown.

Parameters:

attributeNameIndex - the attribute_name_index of the new LocalVariableTypeTableAttribute instance

Returns:

a new LocalVariableTypeTableAttribute instance

Throws:

java.lang.IllegalArgumentException - thrown if, and only if, attributeNameIndex is less than or equal to 0
