Public Methods
public float[] getFloatArray ()
Returns a float array of the values stored in this buffer. If the buffer is of different types
than float, the values will be converted into float. For example, values in TensorBufferUint8
will be converted from uint8 to float.
public float getFloatValue (int index)
Returns a float value at a given index. If the buffer is of different types than float, the
value will be converted into float. For example, when reading a value from TensorBufferUint8
, the value will be first read out as uint8, and then will be converted from
uint8 to float.
For example, a TensorBuffer with shape {2, 3} that represents the following array, [[0.0f, 1.0f, 2.0f], [3.0f, 4.0f, 5.0f]]. The fourth element (whose value is 3.0f) in the TensorBuffer can be retrieved by: float v = tensorBuffer.getFloatValue(3);
Parameters
index | The absolute index of the value to be read. |
---|
public int[] getIntArray ()
Returns an int array of the values stored in this buffer. If the buffer is of different type
than int, the values will be converted into int, and loss of precision may apply. For example,
getting an int array from a TensorBufferFloat
with values {400.32f, 23.04f}, the output
is {400, 23}.
public int getIntValue (int index)
Returns an int value at a given index. If the buffer is of different types than int, the value
will be converted into int. For example, when reading a value from TensorBufferFloat
,
the value will be first read out as float, and then will be converted from float to int. Loss
of precision may apply.
For example, a TensorBuffer with shape {2, 3} that represents the following array, [[0.0f, 1.0f, 2.0f], [3.0f, 4.0f, 5.0f]]. The fourth element (whose value is 3.0f) in the TensorBuffer can be retrieved by: int v = tensorBuffer.getIntValue(3); Note that v is converted from 3.0f to 3 as a result of type conversion.
Parameters
index | The absolute index of the value to be read. |
---|
public int getTypeSize ()
Returns the number of bytes of a single element in the array. For example, a float buffer will return 4, and a byte buffer will return 1.
public void loadArray (int[] src, int[] shape)
Loads an int array into this buffer with specific shape. If the buffer is of different types
than int, the values will be converted into the buffer's type before being loaded into the
buffer, and loss of precision may apply. For example, loading an int array with values {400,
-23} into a TensorBufferUint8
, the values will be clamped to [0, 255] and then be
casted to uint8 by {255, 0}.
Parameters
src | The source array to be loaded. |
---|---|
shape | Shape of the tensor that src represents. |
