Field Detail

NUMBER_AS_INTEGER

public static final TypeHandler<java.lang.Number> NUMBER_AS_INTEGER

Converts a Number into a PCP signed 32-bit integer. May cause loss of precision if the supplied Number can not be reasonably coerced into an integer.

NUMBER_AS_LONG

public static final TypeHandler<java.lang.Number> NUMBER_AS_LONG

Converts a Number into a PCP signed 64-bit integer. May cause loss of precision if the supplied Number has a floating-point component.

NUMBER_AS_DOUBLE

public static final TypeHandler<java.lang.Number> NUMBER_AS_DOUBLE

Converts a Number into a PCP double. May cause loss of precision if the supplied Number is not a double.

NUMBER_AS_FLOAT

public static final TypeHandler<java.lang.Number> NUMBER_AS_FLOAT

Converts a Number into a PCP double. May cause loss of precision if the supplied Number is not a float.

BOOLEAN_AS_INT

public static final TypeHandler<java.lang.Boolean> BOOLEAN_AS_INT

Converts a Boolean into a PCP signed 32-bit integer.

ATOMIC_BOOLEAN_AS_INT

public static final TypeHandler<java.util.concurrent.atomic.AtomicBoolean> ATOMIC_BOOLEAN_AS_INT

Converts an AtomicBoolean into a PCP unsigned 32-bit integer.

Method Detail

getDefaultMappings

public static java.util.Map<java.lang.Class<?>,TypeHandler<?>> getDefaultMappings()

Returns:

a standard set of handlers to convert some common Java types (including the java.util.concurrent Atomic primitives) to the most suitable default TypeHandler, without a loss of precision.
