Method Detail

build

public oracle.pgx.common.mutations.PartitionizingStrategy build()

Description copied from class: MutationStrategyBuilder

Builds the MutationStrategy with the chosen parameters. Parameters that were not set, are instantiated with default values.

Specified by:

build in class MutationStrategyBuilder<PartitionizingStrategyBuilder>

Returns:

the strategy

generateDegreeCaches

public PartitionizingStrategyBuilder generateDegreeCaches(boolean doGenerateDegreeCaches)

Set the flag indicating if the degree caches should be generated after the mutation

Parameters:

doGenerateDegreeCaches - boolean flag to indicate if the degree caches should be generated or not

Returns:

the reference to the strategy, after modification of the flag

generateLabelHistogram

public PartitionizingStrategyBuilder generateLabelHistogram(boolean doGenerateLabelHistogram)

Set the flag indicating if the label histogram should be generated after the mutation

Parameters:

doGenerateLabelHistogram - boolean flag to indicate if the histogram should be generated or not

Returns:

the reference to the strategy, after modification of the flag

preserveEdgeKeys

public PartitionizingStrategyBuilder preserveEdgeKeys(boolean doPreserveEdgeKeys)

Set the flag indicating if the edge keys should be preserved in the graph that is partitioned while loading if not, the partitioned graph will not keep the original edge keys

Parameters:

doPreserveEdgeKeys - boolean flag to indicate if the edge keys should be preserved or not

Returns:

the reference to the strategy, after modification of the flag

setDefaultEdgeTableName

public PartitionizingStrategyBuilder setDefaultEdgeTableName(java.lang.String name)

Parameters:

name - the desired default table name

setDefaultVertexTableName

public PartitionizingStrategyBuilder setDefaultVertexTableName(java.lang.String name)

Parameters:

name - the desired default table name

setEdgeLabelToTableNameMap

public PartitionizingStrategyBuilder setEdgeLabelToTableNameMap(java.util.Map<java.lang.String,java.lang.String> map)

Parameters:

map - the desired mapping from edge label to table name

Parameters:

map - the desired mapping from property names to default values

setNewGraphName

public PartitionizingStrategyBuilder setNewGraphName(java.lang.String name)

Description copied from class: MutationStrategyBuilder

Set name of new graph name. If null, the new graphname will be generated.

Overrides:

setNewGraphName in class MutationStrategyBuilder<PartitionizingStrategyBuilder>

Parameters:

name - the desired name for the graph that is partitioned while loading

setVertexLabelsToTableNameMap
