Method Detail

accepts

public boolean accepts(Object value)

Description copied from class: TypeCodec

Return true if this codec is capable of serializing the given object. Note that the object's Java type is inferred from the object' runtime (raw) type, contrary to TypeCodec.accepts(TypeToken) which is capable of handling generic types.

This method is intended mostly to be used by the QueryBuilder when no type information is available when the codec is used.

Implementation notes:

1. The base implementation provided here can only handle non-parameterized types; codecs handling parameterized types, such as collection types, must override this method and perform some sort of "manual" inspection of the actual type parameters.
2. Similarly, codecs that only accept a partial subset of all possible values, such as TypeCodec.TimeUUIDCodec or TypeCodec.AsciiCodec, must override this method and manually inspect the object to check if it complies or not with the codec's limitations.

Overrides:

accepts in class TypeCodec<String>

Parameters:

value - The Java type this codec should serialize from and deserialize to; cannot be null.

Returns:

true if the codec is capable of serializing the given javaType, and false otherwise.
