Method Detail

getBasePath

public java.lang.String getBasePath()

base path to use for storing a graph; file paths will be constructed using the following format <base_path>_<partition_index>.<extension>_, i.e. parent_path/my_graph_1.edges

Specified by:

getBasePath in class AbstractFileGraphStoringConfig

Returns:

the base path

getCompressionScheme

getInitialPartitionIndex

public java.lang.Integer getInitialPartitionIndex()

the value used as initial partition index, i.e. initial_partition_index=1024 -> my_graph_1024.edges, my_graph_1025.edges

Specified by:

getInitialPartitionIndex in class AbstractFileGraphStoringConfig

Returns:

the inital partition index

getNumPartitions

public java.lang.Integer getNumPartitions()

the number of partitions that should be created, when exporting to multiple files

getNumPartitions in class AbstractFileGraphStoringConfig

Returns:

the number of partitions

getValues

public java.util.Map<FileGraphStoringConfig.Field,java.lang.Object> getValues()

Gets the parsed values.

Returns:

the parsed values

getValuesWithoutDefaults

public java.util.Map<FileGraphStoringConfig.Field,java.lang.Object> getValuesWithoutDefaults()

Gets the values without defaults.

Returns:

the values without defaults

getVertexExtension

public java.lang.String getVertexExtension()

the extension to use when creating vertex file partitions

Specified by:

getVertexExtension in class AbstractFileGraphStoringConfig

Returns:

the extension

hasDefaultValue

public boolean hasDefaultValue(FileGraphStoringConfig.Field field)

Checks for default value.

Parameters:

field - the field

Returns:

true, if value for given field is the default value

isEmpty

public boolean isEmpty()

Checks if it's empty.

Returns:

true, if the Map 'values' is empty.

parse

public static FileGraphStoringConfig parse(java.io.InputStream is,
                                           boolean strict,
