RangePartition

public RangePartition()

RangePartition

public RangePartition(java.lang.String connectionPool,
                      java.lang.String partitionValueTypeName,
                      java.lang.String startValueName,
                      java.lang.String endValueName)

INTERNAL: COnstructor used from metadata processing to avoid classloader dependencies. Class names are converted/initialized in the convertClassNamesToClasses method.

RangePartition

public RangePartition(java.lang.String connectionPool,
                      java.lang.Comparable startValue,
                      java.lang.Comparable endValue)

PUBLIC: Create the partition for the connectionPool and start/end values.

Method Detail

convertClassNamesToClasses

public void convertClassNamesToClasses(java.lang.ClassLoader classLoader)

INTERNAL: Convert all the class-name-based settings to actual class-based settings. This method is used when converting a project that has been built with class names to a project with classes.

getStartValue

public java.lang.Comparable getStartValue()

PUBLIC: Return the range start value. Values greater or equal to this value are part of this partition.

initObject

protected java.lang.Object initObject(java.lang.Class type,
                                      java.lang.String value)

INTERNAL: TODO: clean up the exception handling.

setStartValue

public void setStartValue(java.lang.Comparable startValue)

PUBLIC: Set the range start value. Values greater or equal to this value are part of this partition.

getEndValue

public java.lang.Comparable getEndValue()

PUBLIC: Return the range end value. Values less than or equal this value are part of this partition.

setEndValue

public void setEndValue(java.lang.Comparable endValue)

PUBLIC: Set the range end value. Values less than or equal this value are part of this partition.

getConnectionPool

public java.lang.String getConnectionPool()

PUBLIC: Return the connection pool to use for this partition.

setConnectionPool

public void setConnectionPool(java.lang.String connectionPool)

PUBLIC: Return the connection pool to use for this partition.

isInRange

public boolean isInRange(java.lang.Object value)

INTERNAL: Return if the value is in the partitions range.
