All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<OracleInMemoryProperties.InMemoryCompression>

```
Compression methods for table data store in the in-memory column store.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`FOR_CAPACITY` Specifying CAPACITY is equivalent to specifying CAPACITY LOW.
`FOR_CAPACITY_HIGH` This method compresses in-memory data the most and results in good query performance.
`FOR_CAPACITY_LOW` This method compresses in-memory data more than QUERY HIGH, but less than CAPACITY HIGH, and results in excellent query performance.
`FOR_DML` This method is optimized for DML operations and performs little or no data compression.
`FOR_QUERY` Specifying QUERY is equivalent to specifying QUERY LOW.
`FOR_QUERY_HIGH` This method compress in-memory data more than QUERY LOW, but less than CAPACITY LOW.
`FOR_QUERY_LOW` This method compresses in-memory data the least (except for DML) and results in the best query performance.
`NO_MEMCOMPRESS` No memory compression.

- Enum Constant Detail
  - NO_MEMCOMPRESS
```
public static final OracleInMemoryProperties.InMemoryCompression NO_MEMCOMPRESS
```
    No memory compression.
  - FOR_DML
```
public static final OracleInMemoryProperties.InMemoryCompression FOR_DML
```
    This method is optimized for DML operations and performs little or no data compression.
  - FOR_QUERY
```
public static final OracleInMemoryProperties.InMemoryCompression FOR_QUERY
```
    Specifying QUERY is equivalent to specifying QUERY LOW.
  - FOR_QUERY_LOW
```
public static final OracleInMemoryProperties.InMemoryCompression FOR_QUERY_LOW
```
    This method compresses in-memory data the least (except for DML) and results in the best query performance. This is the default.
  - FOR_QUERY_HIGH
```
public static final OracleInMemoryProperties.InMemoryCompression FOR_QUERY_HIGH
```
    This method compress in-memory data more than QUERY LOW, but less than CAPACITY LOW.
  - FOR_CAPACITY
```
public static final OracleInMemoryProperties.InMemoryCompression FOR_CAPACITY
```
    Specifying CAPACITY is equivalent to specifying CAPACITY LOW.
  - FOR_CAPACITY_LOW
```
public static final OracleInMemoryProperties.InMemoryCompression FOR_CAPACITY_LOW
```
    This method compresses in-memory data more than QUERY HIGH, but less than CAPACITY HIGH, and results in excellent query performance.
  - FOR_CAPACITY_HIGH
```
public static final OracleInMemoryProperties.InMemoryCompression FOR_CAPACITY_HIGH
```
    This method compresses in-memory data the most and results in good query performance.
- Method Detail
  - values
```
public static OracleInMemoryProperties.InMemoryCompression[] 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 (OracleInMemoryProperties.InMemoryCompression c : OracleInMemoryProperties.InMemoryCompression.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static OracleInMemoryProperties.InMemoryCompression 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
  - toString
```
public java.lang.String toString()
```
    Custom toString() implementation that returns the syntax for the chosen compression option.
    
    Overrides:
    
    toString in class java.lang.Enum<OracleInMemoryProperties.InMemoryCompression>
    
    Returns:
    
    the syntax
