Detailed Description

A table is a data structure that allows editing of a look up table with a TableEditor.

It uses a list of graph points to create a path which is rendered to a float array of the desired size.

Member Enumeration Documentation

enum DataType

A Table can use two data types.

Enumerator
Midi	in this mode, the table contains 128 elements and can be used for everything midi-related.
SampleLookupTable	in this mode, the table contains 2048 elements and can be used for holding everything sample-related (waveforms, envelopes, etc.)

Constructor & Destructor Documentation

Table

(

)

Creates a new table of the specified type.

Member Function Documentation

void createPath

(

Path &

normalizedPath

)

const

This generates a normalized path from the GraphPoint array.

This is called by the editor to draw the path under the DragPoints.

virtual String exportData ( ) const

inlinevirtual

Exports the data as base64 encoded String.

This is not a ValueTree (so RestorableObject is no base class from Table), because it needs to be embedded in an XML attribute

See also

restoreData()

void fillLookUpTable ( )

virtual

Fills the look up table with the graph points generated from calculateGraphPoints()

Don't call this too often as it is quite heavy!

GraphPoint getGraphPoint ( int  pointIndex ) const

inline

Get a copy of the graph point at pointIndex.

virtual int getTableSize ( ) const

pure virtual

Overwrite this and return the table size.

virtual float* getWritePointer ( )

pure virtual

Overwrite this and return a pointer to the data array.

String getXValueText ( float  value )

inline

This returns a String that can be used for displaying purposes.

You can supply a lambda for the conversion using setTextConverter().

virtual void restoreData ( const String &  savedString )

inlinevirtual

Restores the data from a base64 encoded String.

exportData()

void setGraphPoints	(	const Array< GraphPoint > &	newGraphPoints,
		int	numPoints
	)

Sets the GraphPoints.

If you need to refresh the internal table, you also have to call fillLookUpTable().
