Copy makes a fully independent copy of a profile.

Close closes the file, releasing associated resources.

PrintErr shows an error message to the user. It formats the text as fmt.Print would and adds a final \n if not already present. For line-based UI, Pri

Name returns the underlying file name, if available.

Scale a measurement from a unit to a different unit and returns the scaled value and the target unit. The returned target unit will be empty if uninte

Write writes the profile as a gzip-compressed marshaled protobuf.

testSample returns a profile sample with specified value and stack. Note: callees come first in sample stacks.

set sets the value of field f in cfg to value.

FlatValue returns the exclusive value for this tag, computing the mean if a divisor is available.

Percentage computes the percentage of total of a value, and encodes it as a string. At least two digits of precision are printed.

Bool, Int, Float64, and String define new flags, like the functions of the same name in package flag.

PrintableName calls the Node's Formatter function with a single space separator.

Parse initializes the flags with their values for this run and returns the non-flag command line arguments. If an unknown flag is encountered or there

Sort reorders a slice of nodes based on the specified ordering criteria. The result is sorted in decreasing order for (absolute) numeric quantities, a

Parse parses a profile and checks for its validity. The input may be a gzip-compressed encoded protobuf or one of many legacy profile formats which ma

get returns the value of field f in cfg.

Diff compares two byte arrays using the diff tool to highlight the differences. It is meant for testing purposes to display the differences between ex

Print shows a message to the user. It formats the text as fmt.Print would and adds a final \n if not already present. For line-based UI, Print writes

valueOrDot formats a value according to a report, intercepting zero values.

CumValue returns the inclusive value for this tag, computing the mean if a divisor is available.

Merge merges all the profiles in profs into a single Profile. Returns a new profile independent of the input profiles. The merged profile is compacted

New builds a new report indexing the sample values interpreting the samples with the provided function.

Number of nodelets for labels (both numeric and non) ComposeDot creates and writes a in the DOT format to the writer, using the configurations given.

ProfileLabels returns printable labels for a profile.

makeTestStacks generates a StackSet from a supplied list of samples.

ObjAddr returns the objdump address corresponding to a runtime address.

addrInfo returns the stack frame information for a specific program address. It returns nil if the address could not be identified.

awayFromTTY saves the output in a file if it would otherwise go to the terminal screen. This is used to avoid dumping binary data on the screen.

configure stores the name=value mapping into the current config, correctly handling the case when name identifies a particular choice in a field.

defaultConfig returns the default configuration values; it is unaffected by flags and interactive assignments.

write appends a null-terminated string and returns its starting index.

Aggregate merges the locations in the profile into equivalence classes preserving the request attributes. It also updates the samples to point to the

CheckValid tests whether the profile is valid. Checks include, but are not limited to: - len(Profile.Sample[n].value) == len(Profile.value_unit) - Sam

ScaledLabel scales the passed-in measurement (if necessary) and returns the label used to describe a float measurement.

SortTags sorts a slice of tags based on their weight.

SourceLine reports the source line information for a given address in the file. Due to inlining, the source line information is in general a list of p

Sum adds the flat and cum values of a set of nodes.

Symbols returns a list of symbols in the object file. If r is not nil, Symbols restricts the list to symbols with names matching the regular expressio

compareNodes compares two nodes to provide a deterministic ordering between them. Two nodes cannot have the same Node.Info value.

createEdges creates directed edges from the parent to each of the children.

escapeForDot escapes double quotes and backslashes, and replaces Graphviz's "center" character (\n) with a left-justified character. See https://graph

makeReport generates a report for the specified command. If configEditor is not null, it is used to edit the config used for the report.

newTrimmedGraph creates a graph for this report, trimmed according to the report options.

render responds with html generated by passing data to the named template.

setDefaults returns a new plugin.Options with zero fields sets to sensible defaults.

Label returns the label used to describe a certain measurement.

LargeProfile returns a large profile that may be useful in benchmarks. If the flag --large_profile is set, the contents of the file named by the flag

New returns a round tripper for making requests with the specified cert, key, and ca. The flags tls_cert, tls_key, and tls_ca are added to the flagset

Normalize normalizes the source profile by multiplying each value in profile by the ratio of the sum of the base profile's values of that sample type

Open satisfies the plugin.ObjTool interface.

address returns the synthetic address for loc, creating one if needed.

callgrindName implements the callgrind naming compression scheme. For names not previously seen returns "(N) name", where N is a unique index. For nam

computeBase computes the relocation base for the given binary file only if the elfMapping field is set. It populates the base and isData fields and re
