Constructor Detail

FieldImpl

public FieldImpl(Field parent,
                 String name)

Construct field implementation.

Parameters:

parent - The parent of the field.

name - The name of the field.

Method Detail

getParent

public Field getParent()

Gets the parent of the field.

Returns:

The parent of the field.

getName

public String getName()

Gets the name of the field.

Returns:

The name of the field.

toString

public StringBuilder toString(StringBuilder sb)

Append a string representation of the object to the given StringBuilder. In general, the toString method for query objects appends a string that textually represents this object. The result should be a query string that complies to EJB QL specification as long as the query object represents a syntay element of it. It is required that all subclasses override this method. The toString method defined at class Object is overwritten and calls this method.

Parameters:

sb - StringBuilder to append the string representation of this object to.

Returns:

Same instance of StringBuilder given as parameter.
