Method Detail

asByte

NumericQueryStepBuilder<S,java.lang.Byte> asByte()

Converts the elements in the current result set into Bytes.

This method first checks if the element in question is an instance of Byte. If it is a Byte, it is cast down and forwarded. Otherwise, it is discarded, i.e. all non-Bytes will be filtered out. All null values will also be filtered out.

Returns:

The step builder, for method chaining. Never null.

asShort

NumericQueryStepBuilder<S,java.lang.Short> asShort()

Converts the elements in the current result set into Shorts.

This method first checks if the element in question is an instance of Short. If it is a Short, it is cast down and forwarded. Otherwise, it is discarded, i.e. all non-Shorts will be filtered out. All null values will also be filtered out.

Returns:

The step builder, for method chaining. Never null.

asInteger

NumericQueryStepBuilder<S,java.lang.Integer> asInteger()

Converts the elements in the current result set into Integers.

This method first checks if the element in question is an instance of Integer. If it is a Integer, it is cast down and forwarded. Otherwise, it is discarded, i.e. all non-Integers will be filtered out. All null values will also be filtered out.

Returns:

The step builder, for method chaining. Never null.

asLong

NumericQueryStepBuilder<S,java.lang.Long> asLong()

Converts the elements in the current result set into Longs.

This method first checks if the element in question is an instance of Long. If it is a Long, it is cast down and forwarded. Otherwise, it is discarded, i.e. all non-Longs will be filtered out. All null values will also be filtered out.

Returns:

The step builder, for method chaining. Never null.

asFloat

NumericQueryStepBuilder<S,java.lang.Float> asFloat()

Converts the elements in the current result set into Floats.

This method first checks if the element in question is an instance of Float. If it is a Float, it is cast down and forwarded. Otherwise, it is discarded, i.e. all non-Floats will be filtered out. All null values will also be filtered out.

Returns:

The step builder, for method chaining. Never null.

asDouble

NumericQueryStepBuilder<S,java.lang.Double> asDouble()

Converts the elements in the current result set into Doubles.

This method first checks if the element in question is an instance of Double. If it is a Double, it is cast down and forwarded. Otherwise, it is discarded, i.e. all non-Doubles will be filtered out. All null values will also be filtered out.

Returns:

The step builder, for method chaining. Never null.
