Class Buffer

Namespace

easyar

Assembly

EasyAR.Sense.dll

Buffer stores a raw byte array and can be used to access image data. In the Java API, you can get a buffer from `Image`_ and then copy data to a Java byte array. In all versions of EasyAR Sense, you can access image data. See `Image`_.

Methods

copyFromByteArray(byte[])

public void copyFromByteArray(byte[] src)

Parameters

src

copyFromByteArray(byte[], int, int, int)

public void copyFromByteArray(byte[] src, int srcIndex, int index, int length)

Parameters

src

srcIndex

index

length

copyToByteArray(byte[])

public void copyToByteArray(byte[] dest)

Parameters

dest

copyToByteArray(int, byte[], int, int)

public void copyToByteArray(int index, byte[] dest, int destIndex, int length)

Parameters

index

dest

destIndex

length

create(int)

Creates a Buffer with the specified byte length.

public static Buffer create(int size)

Parameters

size

data()

Returns the raw memory address.

public virtual IntPtr data()

memoryCopy(IntPtr, IntPtr, int)

Copies raw memory. Mainly used for languages or environments with incomplete memory operations.

public static void memoryCopy(IntPtr src, IntPtr dest, int length)

Parameters

src

dest

length

partition(int, int)

Creates a sub-Buffer and references the original Buffer. A Buffer is released only after all sub-Buffers are released.

public virtual Buffer partition(int index, int length)

Parameters

index

length

size()

Byte length of the Buffer.

public virtual int size()

tryCopyFrom(IntPtr, int, int, int)

Attempts to copy data from a raw memory address into a Buffer. Returns true if copying succeeds, otherwise false. Failure reasons include the source data range or target data range exceeding the available range.

public virtual bool tryCopyFrom(IntPtr src, int srcIndex, int index, int length)

Parameters

src

srcIndex

index

length

tryCopyTo(int, IntPtr, int, int)

Attempts to copy data from a Buffer to a raw memory address. Returns true if copying succeeds, otherwise false. Failure reasons include the source data range or target data range exceeding the available range.

public virtual bool tryCopyTo(int index, IntPtr dest, int destIndex, int length)

Parameters

index

dest

destIndex

length

wrap(IntPtr, int, Action)

Wraps a raw memory block of a specified length. When the Buffer is fully released, the deleter callback is called to execute user-defined memory destruction behavior. deleter must be thread-safe.

public static Buffer wrap(IntPtr ptr, int size, Action deleter)

Parameters

ptr

size

deleter

wrapByteArray(byte[])

public static Buffer wrapByteArray(byte[] bytes)

Parameters

bytes

wrapByteArray(byte[], int, int)

public static Buffer wrapByteArray(byte[] bytes, int index, int length)

Parameters

bytes

index

length

wrapByteArray(byte[], int, int, Action)

public static Buffer wrapByteArray(byte[] bytes, int index, int length, Action deleter)

Parameters

bytes

index

length

deleter
