Examples with ByteBuffer java.nio.ByteBuffer used on opensource projects

Example 46 with ByteBuffer

use of java.nio.ByteBuffer in project titan by thinkaurelius.

the class BufferUtil method getLongBuffer.

public static final StaticBuffer getLongBuffer(long id) {
    ByteBuffer buffer = ByteBuffer.allocate(longSize);
    buffer.putLong(id);
    byte[] arr = buffer.array();
    Preconditions.checkArgument(arr.length == longSize);
    return StaticArrayBuffer.of(arr);
}

Example 47 with ByteBuffer

use of java.nio.ByteBuffer in project titan by thinkaurelius.

the class BufferUtil method getIntBuffer.

public static final StaticBuffer getIntBuffer(int[] ids) {
    ByteBuffer buffer = ByteBuffer.allocate(intSize * ids.length);
    for (int i = 0; i < ids.length; i++) buffer.putInt(ids[i]);
    byte[] arr = buffer.array();
    Preconditions.checkArgument(arr.length == intSize * ids.length);
    return StaticArrayBuffer.of(arr);
}

Example 48 with ByteBuffer

use of java.nio.ByteBuffer in project playn by threerings.

the class JavaGL20 method glGetShaderInfoLog.

@Override
public String glGetShaderInfoLog(int shader) {
    ByteBuffer buffer = ByteBuffer.allocateDirect(1024 * 10);
    buffer.order(ByteOrder.nativeOrder());
    ByteBuffer tmp = ByteBuffer.allocateDirect(4);
    tmp.order(ByteOrder.nativeOrder());
    IntBuffer intBuffer = tmp.asIntBuffer();
    GL20.glGetShaderInfoLog(shader, intBuffer, buffer);
    int numBytes = intBuffer.get(0);
    byte[] bytes = new byte[numBytes];
    buffer.get(bytes);
    return new String(bytes);
}

Example 49 with ByteBuffer

use of java.nio.ByteBuffer in project playn by threerings.

the class JavaGL20 method glTexSubImage3D.

@Override
public void glTexSubImage3D(int target, int level, int xoffset, int yoffset, int zoffset, int width, int height, int depth, int format, int type, int pixels) {
    final ByteBuffer byteBuffer = BufferUtils.createByteBuffer(1);
    byteBuffer.putInt(pixels);
    byteBuffer.rewind();
    GL12.glTexSubImage3D(target, level, xoffset, yoffset, zoffset, width, height, depth, format, type, byteBuffer);
}

Example 50 with ByteBuffer

    ByteBuffer bbuf = bufs.createByteBuffer(MAX_LOG_SIZE);
    glGetShaderInfoLog(shader, MAX_LOG_SIZE, bufs.intBuffer, bbuf);
    return toString(bbuf, bufs.intBuffer.get(0));
}
