Method Detail

create

public static Uint8Array create(int length)

Create a new ArrayBuffer with enough bytes to hold length elements of this typed array, then creates a typed array view referring to the full buffer.

Parameters:

length -

create

public static Uint8Array create(TypeArray array)

Create a new ArrayBuffer with enough bytes to hold array.length elements of this typed array, then creates a typed array view referring to the full buffer. The contents of the new view are initialized to the contents of the given typed array or sequence, with each element converted to the appropriate typed array type.

Parameters:

array -

create

public static Uint8Array create(int... array)

Create a new ArrayBuffer with enough bytes to hold array.length elements of this typed array, then creates a typed array view referring to the full buffer. The contents of the new view are initialized to the contents of the given typed array or sequence, with each element converted to the appropriate typed array type.

Parameters:

array -

create

public static Uint8Array create(com.google.gwt.core.client.JsArrayInteger array)

Create a new ArrayBuffer with enough bytes to hold array.length elements of this typed array, then creates a typed array view referring to the full buffer. The contents of the new view are initialized to the contents of the given typed array or sequence, with each element converted to the appropriate typed array type.

Parameters:

array -

create

public static Uint8Array create(ArrayBuffer buffer)

Create a new Uint8Array object using the passed ArrayBuffer for its storage. The Uint8Array spans the entire ArrayBuffer range.

Parameters:

buffer -

create

public static Uint8Array create(ArrayBuffer buffer,
                                int byteOffset)

Create a new Uint8Array object using the passed ArrayBuffer for its storage. The Uint8Array extends from the given byteOffset until the end of the ArrayBuffer. The given byteOffset must be a multiple of the element size of the specific type, otherwise an INDEX_SIZE_ERR exception is raised. If a given byteOffset references an area beyond the end of the ArrayBuffer an INDEX_SIZE_ERR exception is raised. The length of the ArrayBuffer minus the byteOffset must be a multiple of the element size of the specific type, or an INDEX_SIZE_ERR exception is raised.

Parameters:

buffer -

byteOffset - indicates the offset in bytes from the start of the ArrayBuffer

create

public static Uint8Array create(ArrayBuffer buffer,
                                int byteOffset,
                                int length)

Create a new Uint8Array object using the passed ArrayBuffer for its storage. The given byteOffset must be a multiple of the element size of the specific type, otherwise an INDEX_SIZE_ERR exception is raised. If a given byteOffset and length references an area beyond the end of the ArrayBuffer an INDEX_SIZE_ERR exception is raised.

Parameters:

buffer -

byteOffset - indicates the offset in bytes from the start of the ArrayBuffer

length - the count of elements from the offset that this Uint8Array will reference

get

public int get(int index)

Returns the element at the given numeric index.

Parameters:

index -

set

public void set(int index,
                int value)

Sets the element at the given numeric index to the given value.

Parameters:

index -

value -

set

public void set(com.google.gwt.core.client.JsArrayInteger array)

Set multiple values, reading input values from the array.

set

public void set(com.google.gwt.core.client.JsArrayInteger array,
                int offset)

/** Set multiple values, reading input values from the array.

Parameters:

array -

offset - indicates the index in the current array where values are written.

slice

public Uint8Array slice(int begin)

Returns a new Uint8Array view of the ArrayBuffer store for this Uint8Array, referencing the elements at begin, inclusive, up to end, exclusive. If either begin or end is negative, it refers to an index from the end of the array, as opposed to from the beginning. The slice contains all elements from begin to the end of the Uint8Array. The range specified by the begin and end values is clamped to the valid index range for the current array. If the computed length of the new Uint8Array would be negative, it is clamped to zero. The returned Uint8Array will be of the same type as the array on which this method is invoked.

Parameters:

begin -

slice

public Uint8Array slice(int begin,
                        int end)

Returns a new Uint8Array view of the ArrayBuffer store for this Uint8Array, referencing the elements at begin, inclusive, up to end, exclusive. If either begin or end is negative, it refers to an index from the end of the array, as opposed to from the beginning. The slice contains all elements from begin to the end of the Uint8Array. The range specified by the begin and end values is clamped to the valid index range for the current array. If the computed length of the new Uint8Array would be negative, it is clamped to zero. The returned Uint8Array will be of the same type as the array on which this method is invoked.

Parameters:

begin -

end -
