Uses of Hop in org.apache.sysds.hops

Subclasses of Hop in org.apache.sysds.hops

Modifier and Type	Class	Description
class	AggBinaryOp
class	AggUnaryOp
class	BinaryOp
class	DataGenOp	A DataGenOp can be rand (or matrix constructor), sequence, and sample - these operators have different parameters and use a map of parameter type to hop position.
class	DataOp	A DataOp can be either a persistent read/write or transient read/write - writes will always have at least one input, but all types can have parameters (e.g., for csv literals of delimiter, header, etc).
class	DnnOp
class	FunctionOp	This FunctionOp represents the call to a DML-bodied or external function.
class	IndexingOp
class	LeftIndexingOp
class	LiteralOp
class	MultiThreadedHop	Optional hop interface, to be implemented by multi-threaded hops.
class	NaryOp	The NaryOp Hop allows for a variable number of operands.
class	ParameterizedBuiltinOp	Defines the HOP for calling an internal function (with custom parameters) from a DML script.
class	QuaternaryOp	Note: this hop should be called AggQuaternaryOp in consistency with AggUnaryOp and AggBinaryOp; however, since there does not exist a real QuaternaryOp yet - we can leave it as is for now.
class	ReorgOp	Reorg (cell) operation: aij Properties: Symbol: ', rdiag, rshape, rsort 1 Operand (except sort and reshape take additional arguments) Semantic: change indices (in mapper or reducer) NOTE MB: reshape integrated here because (1) ParameterizedBuiltinOp requires name-value pairs for params and (2) most importantly semantic of reshape is exactly a reorg op.
class	TernaryOp	Primary use cases for now, are quantile (<n-1-matrix>, <n-1-matrix>, <literal>): quantile (A, w, 0.5) quantile (<n-1-matrix>, <n-1-matrix>, <scalar>): quantile (A, w, s) interquantile (<n-1-matrix>, <n-1-matrix>, <scalar>): interquantile (A, w, s) Keep in mind, that we also have binaries for it w/o weights.
class	UnaryOp
