Method Details

getCurrentVectorSize

public int getCurrentVectorSize()

Description copied from interface: VectorSizeInspector

Returns the current vector size for this cursor. Will never be larger than the max size returned by VectorSizeInspector.getMaxVectorSize().

Specified by:

getCurrentVectorSize in interface VectorSizeInspector

getMaxVectorSize

public int getMaxVectorSize()

Description copied from interface: VectorSizeInspector

Returns the maximum vector size for this cursor. It will not change for the lifetime of this cursor, and is generally used to allocate scratch arrays for later processing. Will always be greater than zero.

Specified by:

getMaxVectorSize in interface VectorSizeInspector

getLongVector

public long[] getLongVector()

Description copied from interface: VectorValueSelector

Get the current vector, casting to longs as necessary. The array will be reused, so it is not a good idea to retain a reference to it.

Specified by:

getLongVector in interface VectorValueSelector

getFloatVector

public float[] getFloatVector()

Description copied from interface: VectorValueSelector

Get the current vector, casting to floats as necessary. The array will be reused, so it is not a good idea to retain a reference to it.

Specified by:

getFloatVector in interface VectorValueSelector
