Constructor Detail

SequenceFieldType

public SequenceFieldType(FieldType<E> elementType)

Construct a new field type representing a sequence whose members are all of a given field type. This constructor is provided for backwards compatibility, the recommended way to construct this field type is with FieldTypes.sequence(FieldType).

Parameters:

elementType - type of elements this sequence contains

See Also:

FieldTypes.sequence(FieldType)

Method Detail

getElementType

public FieldType<E> getElementType()

Get the type of the elements.

Returns:

the type of sub-elements

assertAssignable

public void assertAssignable(java.lang.Object c,
                             java.lang.String fieldName)

Description copied from class: FieldType

This method is intended for internal use only and may be removed at any time - do not use.

Specified by:

assertAssignable in class FieldType<java.util.List<E>>

parse

public java.util.List<E> parse(java.lang.String value)
                        throws ParserRuntimeException

Convert a value of this type from the format used in Apama event strings, into a List object.

Overrides:

parse in class FieldType<java.util.List<E>>

Parameters:

value - the value to parse.

Returns:

an object specifying the value of the string that was parsed.

Throws:

ParserRuntimeException - If the specified value string cannot be parsed.

toString

public java.lang.String toString()

Description copied from class: FieldType

Returns a String representation of the field type. Note that this representation will use the Java toString() method to format the results, and is not valid monitorscript.

Overrides:

toString in class FieldType<java.util.List<E>>
