Types

type FileContext

type FileContext struct {
	// FileContent is the content of the file to be matched.
	FileContent []byte

	// PackageName is the name of the package given as seen in `package main` for example.
	PackageName string
	// contains filtered or unexported fields
}

func (*FileContext) FileContains

func (ctx *FileContext) FileContains(content string) MatchType

type MatchType

type MatchType byte

MatchType is an enumeration of the possible outcomes of a join point

const (
	// Unknown indicates that the join point cannot determine whether it matches the given context
	Unknown MatchType = '?'
	// Match indicates that the join point may match the given context
	Match MatchType = 'Y'
	// NeverMatch indicates that the join point DOES NOT match the given context
	NeverMatch MatchType = 'N'
)
