Method Detail

readExternalback to summary
public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException

Implements java.io.Externalizable.readExternal.

Doc from java.io.Externalizable.readExternal.

The object implements the readExternal method to restore its contents by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays. The readExternal method must read the values in the same sequence and with the same types as were written by writeExternal.

Parameters
in:ObjectInput

the stream to read data from in order to restore the object

Annotations
@Override
@SuppressWarnings:unchecked
Exceptions
IOException:
if I/O errors occur
ClassNotFoundException:
If the class for an object being restored cannot be found.

public ValueExpression resolveVariable(String variable)

Implements abstract javax.el.VariableMapper.resolveVariable.

Parameters
variable:String

Doc from javax.el.VariableMapper.resolveVariable.

The variable name

Returns:ValueExpression

public ValueExpression setVariable(String variable, ValueExpression expression)

Implements abstract javax.el.VariableMapper.setVariable.

Doc from javax.el.VariableMapper.setVariable.

Assign a ValueExpression to an EL variable, replacing any previously assignment to the same variable. The assignment for the variable is removed if the expression is null.

Parameters
variable:String

The variable name

expression:ValueExpression

The ValueExpression to be assigned to the variable.

Returns:ValueExpression

The previous ValueExpression assigned to this variable, null if there is no previous assignment to this variable.

Doc from java.io.Externalizable.writeExternal.

The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays.

Parameters
out:ObjectOutput

the stream to write the object to
