Constructor Detail

FieldAndVarReader

public FieldAndVarReader(java.lang.String fieldName,
                         java.lang.String variableName)

Creates a new FieldAndVarReader with the given field/variable names.

Both the field and variable names are optional. If a field name is specified, the corresponding field is set to the parsed value, converted to the proper type. If a variable name is specified, the corresponding variable is set to the parsed value. If both are specified, then both are set to the same value, reading only one token from the input.

Specifying neither a field nor a variable name is valid. In this case, this reader consumes one token from the input nonetheless, but no fields nor variables are set as a result.

Parameters:

fieldName - the name of a field of the parent object, or null if no field should be set. The given field has to be of a primitive type or string.

variableName - the name of a variable to set, or null if no variable should be set.
