All Implemented Interfaces:

IntegerValuedEnum, java.io.Serializable, java.lang.Comparable<SoGLBufferObject.Usages>

Enclosing class:

SoGLBufferObject
```
public static enum SoGLBufferObject.Usages
extends java.lang.Enum<SoGLBufferObject.Usages>
implements IntegerValuedEnum
```
This enum declares the possible usages of the memory allocated for the buffer. This is a hint to the OpenGL driver implementation as to how a buffer object's data store will be accessed. This enables the OpenGL implementation to make more intelligent decisions that may significantly impact buffer object performance. It does not, however, constrain the actual usage of the data store. usage can be broken down into two parts: first, the frequency of access (modification and usage - STATIC, STREAM, DYNAMIC), and second, the nature of that access - DRAW, COPY, READ.

- Enum Constant Detail
  - STREAM_DRAW
```
public static final SoGLBufferObject.Usages STREAM_DRAW
```
    The data store contents will be modified once and used at most a few times. The data store contents are modified by the application, and used as the source for GL drawing and image specification commands.

- Method Detail
  - values
```
public static SoGLBufferObject.Usages[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (SoGLBufferObject.Usages c : SoGLBufferObject.Usages.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static SoGLBufferObject.Usages valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - fromValue
```
@Deprecated
public static SoGLBufferObject.Usages fromValue(int val)
```
    Deprecated. Use valueOf(int) instead.
    
    Returns the enum constant of this type with the specified integer value
    
    Returns:
    
    the enum constant of this type with the specified integer value.
  - valueOf
```
public static SoGLBufferObject.Usages valueOf(int val)
```
    Returns the enum constant of this type with the specified integer value
    
    Returns:
    
    the enum constant of this type with the specified integer value.
  - getValue
```
public int getValue()
```
    Description copied from interface: IntegerValuedEnum
    
    Returns the integer value of the enum constant.
    
    Specified by:
    
    getValue in interface IntegerValuedEnum
    
    Returns:
    
    the integer value of the enum constant.
