TypedUniformValueArrayInstance()

TypedUniformValueArrayInstance

(

const ShaderVariableValueArrayDeclaration &

declaration

)

Member Function Documentation

getNumElements()

int getNumElements

(

)

const

Returns

total number of elements in array

getValues()

std::vector<T>& getValues

(

)

Returns

entire array as a reference

operator[]()

T& operator[]

(

size_t

index

)

Array subscript operator, returns a specific value in the array as a reference, making the following possible: mUniformArray[0] = 12;

Returns

a specific value in the array as a reference.

push()

void push ( uint8 *  uniformBuffer ) const

overridevirtual

Pushes the data to the 'Shader'

Parameters

uniformBuffer

the buffer to copy the array into.

Implements UniformLeafInstance.

set()

void set

(

const TypedUniformValueArray< T > &

resource

)

Updates the uniform value from a resource, data is not pushed immediately.

Parameters

resource

resource to copy data from.

setDefault()

virtual void setDefault ( )

overridevirtual

Resize based on shader declaration.

Implements UniformValueArrayInstance.

setValue()

void setValue	(	T	value,
		int	index
	)

Updates a single uniform value in the array, data is not pushed immediately. Note that the given index must be =< than length declared in shader.

Parameters

value	the value to set
index	the index in the array

setValues()

void setValues

(

const std::vector< T > &

values

)

Updates the uniform value, data is not pushed immediately. Note that the length of the given values must be =< than length declared in shader.

Parameters

values

new list of values
